I'm pretty P.O.'d about the quality of these parts from various manufacturers as I started with Purolator PCV's and had them pull apart in two pieces as well as stick (not rattle) shortly after being purchased.
I tried Autozone's DEUTSCH PCV VALVE for a 2000 ISUZU TRUCK VEHICROSS 4WD
Unit Price: $3.49
Part No.: PCV193
Weight: 0.05 lbs.
Availability: Online: Ships within 2 business days
Store: Normally Stocked
only to have them also stick (quit rattling) shortly after purchase. I sometimes wonder if my choice of oil (Mobil 1 Synthetic) isn't causing the PCV's to stick? Also tried a PCV from NAPA made in the USA only to have it stick closed not long after purchase too.
The longest working one I've had so far was one I purchased from some Mom & Pop place in Moab Utah after my newly purchased Purolator stuck closed during my road trip to Moab. But I finally had to replace it after it started to repeatedly stick closed.
I'm currently running one I bought from some Mom & Pop place in Edinboro, PA that I do like in that it has a larger diameter which "seems" to let my VX idle smoother when it is functioning correctly. I've gotten myself into a habit of checking for "rattle" after every fuel stop as I always check the oil level anyways. Usually like every 2nd fuel stop mine isn't rattling and I give it a shot of PB blaster or SeaFoam and then it rattles perfectly for like 2 tanks of gas before sticking again!
When my PCV sticks closed...my breather cap on the opposite valve cover starts foaming oil due to the crankcase pressure building up internally and releasing pressure as well as oil spray out the breather. Kind of nice in that I get a visual indication that the PCV isn't working...however...kind of sucks because I have to top off my oil due to usage/leakage. I swear my idling isn't as smooth too when the darn thing sticks as well. I am wondering if your best bet isn't to stick with the OEM PCV from ISUZU???
I was surprised to see that my '07 Mustang doesn't have a serviceable PCV as per the owners manual...time will tell if this is a great design!
